    This analysis of global and Asian markets looks at protectionism and substitution (decline in starch trade, rise in trade of cassava feedstuffs) and the Asian regional market for cassava feedstuffs. The degree of substitution between cassava and grains has increased measurably during the postwar period. Cassava's future in world markets depends on its ability to compete with grains; so far this has depended on grain pricing policies and tariff structures of importing countries, making cassava trade more vulnerable than the international grain trade.

    Given the monumental challenges facing today's world - widespread poverty, urban blight, illiteracy, tropical deforestation and the threat of nuclear war, to name only a few - it may seem quite irrelevant to devote an issue of Unasylva to the rather tame-sounding subject of urban forestry. To millions of homeless or starving or unemployed people in the urban centres of the developing world, how important can urban forestry really be? In truth, urban forestry, as sometimes practiced, does tend to benefit the well-to-do at the expense of the underprivileged.

    In Thailand cassava is produced mainly for export. The Thai cassava industry was based on starch export until the 60s when West Germany began to use CSW for animal feed. As this was a by-product of starch manufacturing, shortages resulted, leading to the market for CM. Chips became the dominant export in 1964 and so did native pellets in 1969, and hard pellets in 1983. Thailand went from a minor producer of cassava in the 50s to presently the 2nd largest in the world. Data are provided on production trends, yields (av.
